[Apologies for multiple postings]
We're working actively on an Integrity Constraints extension for OWL,
in Pellet, that will make OWL more useful as a data validation
language. We've put together a survey to ask for community feedback
about a variety of questions, including use cases and requirements,
syntax, and semantics.
Please participate in the survey and let us know what you think:

For background information about Integrity Constraints, see
